Hello, I found a posting on the mailing list from 2008 "Adding new storage backend to Dovecot" while searching for POP3 and IMAP servers, that allow to use a NoSQL backend rather than a traditional file system. The problem with traditional filesystems is, that they are very limited. You cannot easily extend it, even with RAID 10 all messages may be lost due to a RAID controller failure and just-in-time backups of a heavy loaded system with consistently ch...

Hi, I'm searching, but not found nothing about using userb with NoSQL databases: http://wiki2.dovecot.org/UserDatabase Are there any plans to implement this option? Thanks

Is there any support for NoSQL databases such as Cassandra (CQL) or MongoDB now or planned in the future for userdb and passdb lookups?

Yes, I?ve read these doc. I was just considering if someone had any experience with Mogile in email environment. Well, actually I?m trying to figure out if one of those nosql systems can store and scale email systems (ie, mailboxes - instead of maildir). I know mysql is always quoted as an option and discussed sometimes in the list. I think it?s an unnecessary overhead and bottleneck. As brainstorm. How about Cassandra, Tokyo-Tirant, Redis, and so on. Have you ever wor...

Hi Elena, Thanks for pushing forward with this. I like the idea of using a NoSQL solution. My primary reservation is about adding the new NoSQL stuff as an extra backend. I think the current database backend and its use of SQLAlchemy is extremely complex and is in fact the most complex part of LNT. Adding something more (as opposed to *replacing* it) would just make this worse...

...d test parameterization I think it's important that it remains simple to get a simple local instance up and running. That will make it easier for people to give LNT a try, and also makes it easier for LNT developers to have everything they need for developing locally. I have no experience with NoSQL database engines. Would it be possible, assuming you have the MongoDB/other packages installed for your system, to just run $ ~/mysandbox/bin/python ~/lnt/setup.py develop $ lnt create ~/myperfdb $ lnt runserver ~/myperfdb and be up and running (which is roughly what is required at the moment)? O...

...data kills the server. I ended up limiting those to a max of 10 datasets, and even that takes 30s to load. So I do think we need some improvements to the scalability. LNT usage is spread between two groups. Users who setup big servers, with Postgres and apache/Gunicorn. For those uses I think a NoSQL is the way to go. However, our second (and probably more common) user, is the people running little instance on their own machine to do some local compiler benchmarking. Their setup process needs to be dead simple, and I think requiring a NoSQL database to be setup on their machine first is a no...

...% of samples want to include arbitrary blobs of extra data. I think standardizing on PostgreSQL/JSON is the right approach here, given the standard PaaS support for PostgreSQL and its existing use within our deployments. SQLAlchemy has native support for this. 4. I don't actually think that a NoSQL database buys us much if anything (particularly when we have PostgreSQL/JSON available). We are not in a situation where we would need something like eventual consistency around writes, which leaves us wanting raw query performance over large sets of relatively well-structured data. I believe that...

...nges will need getting some metrics separately and BLOB format will add some delay in time for queries. As we see now problem of performance is actual, because time for rendering graph page is about 3 minutes. [cid:image001.png at 01D19EFA.6E5F0A70] So maybe it will be better to start working with NoSql databases? I made a small prototype with TestSuite, TestSuiteFields, Test, Run and Sample tables for getting time metrics. It works quickly. And using NoSQL helps solve problems with different fields for samples metrics fields. Then it will be possible to store different metrics for different test...

...il. In this case this option is not really possible. 2) Use new dovecot-2.1 imap backend and develop a kind of dummy imap server listening to a custom port and storing emails inside a mongoDB database. Advantage is it allow replication very easily. 3) Wait for dovecot2.x to implement a NoSQL storage. Will it happen soon ? If you have other suggestions or ideas I would be happy to hear them.

Good day, does anyone here have a clue on how to make use of the NoSQL database "Riak" with Camping? I am building my website and Riak seems like pretty much the ultimate database! This would probably ruin every little feature in ActiveRecord, I don''t think I''d be able to do any has_many''s or belongs_to but I''d LOVE...

...o is that it uses existing IMAP server for mails rather than reimplementing yet another one itself. They seem to prefer Cyrus, but apparently Dovecot should work too. For non-mail (calendar, etc) it uses SQL, but I heard it's not too difficult to replace that either if someone would prefer some NoSQL database or something. http://www.sogo.nu/ http://www.openchange.org/

Hello All - I am trying to use RJSONIO to read in some JSON files. I was wondering if anyone could please comment on the level of complexity of the files it can be used to read, exports from or directly from NoSQL DBMS like MongoDB and such. Also, i understand that in reading the JSON file RJSONIO will automatically create the necessary structures. However I cannot seem to use to to read the file properly and get this error: Error in function (classes, fdef, mtable) : unable to find an inherited method...

...he time. - OpenOffice may well die due to brain drain from LibreOffice. They?ve both got big corporate backers. - The MySQL mailing list is getting a tiny fraction of the traffic it once enjoyed before the Oracle takeover; MySQL won?t go away any time soon for reasons of inertia, but MariaDB and NoSQL are surely taking large bites out of its user base. - Remember ESD and aRTS?
